PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 443,012, dated December 16,1890. Application filed February 25, 1890. Serial No. 341,693. (No model.)

To all whom it may concern,.-

Be it known that I, MORGAN Il. SLY, a citizen of the United States, residing at Alexis, in the county of Warren and State of Illinois, have invented certain new and useful Iniprovements in Printing-Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its objects to produce a simple and economical printing-press whereon newspapers and other large sheet-s may be printed with ease and rapidity and with a minimum amount of labor, the invention being particularly designed to furnish a press having no complicated machinery, and which can be supplied at such cost as to place it within the reach of small establishments.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which- Figure l illustrates a top view of a press constructed according to my invention, showing the impress-cylinder by which the sheet is carried to and impressed upon the type-form in position over the said form. Fig. 2 represents a side elevation showing the impresscylinder in position to receive the sheet and the inking-rollers in position to take the ink previously to applying it to the distributingdisk. Fig. 3 represents a longitudinal vertical sectional view of the press, showing the impress-cylinder in position over the receptacle into which thc papers are delivered and ready to commence operation. Fig. i represents a top view of a part of the press, showing a portion of the inking devices. Fig. 5 represents a perspective view of the ink-distributing disk detached, with a portion broken away, showing' part of the mechanism by which the disk isoperated; and Fig. 6 represents a longitudinal vertical sectional View of the impress-cylinder and a portion of the press-bed in cross-section.

Referring to the drawings, the letter A 1ndicates the bed of the press, which is provided with suitable legs or supports to hold it at a convenient elevation. Near one end of the press it is provided with vertical standards B, which in the present instance are combr nations of two of the supporting-legs, but which may be independent thereof, if desired. To these standards at their upper ends (which are beveled or sloped for the purpose) is secured an inclined table or shelf C, upon which the sheets t-o be printed are placed and from which they are fed. The lower edge of said table or shelf is provided with projecting fingers D, upon which the lower edge of the sheet as fed forward rests until seized to be carried to the type-form, as more fully hereinafter explained. The said sheet is held at the ends of the fingers D until just about to be seized by means of short fingers E, secured to a rail F, the side arms of which are adj ustably secured in socketed heads G, pivoted to the sides of the standards B, so as to permit the rail to be swungV upward at the proper time to release the sheet previous to its removal, the upward movement being effected by means of a cam-arm H, which is secured to one of the sides of the rail and operated by a disk or wheel at one end of the iinpress-cylinder, as will more fully hereinafter appear.

Forward of the standards B, and extending from recesses therein7 are arranged two guiderails B', which are secured to the upper side edges of the press-bed and terminate near the right-hand end thereof. At the said end are'arranged, also, upwardly-curved arms B3, which limit the movement of the impress-cylinder, (indicated by the letter I in the respective figures.) The said cylinder is composed of a solid intermediate section K, having hollow cylindrical heads L at each end, as shown in detail in Fig. 6 of the drawings. The solid section of the cylinder gives it the proper weight to impress the paper upon the typeform, and may vary in length, according to the size of the press. The heads are arranged to travel upon ways M at the top of the pressbed within the rails B as the cylinder traverses the bed. The section K is recesse-d longitudinally at one side and provided with a central bearing N within said recess for a longitudinal shaft P, which extends through the ends of the sections K and is provided with a bend R, under which bears a flat spring S for holding the shaftl in a fixed position. The ends of the shaft within the hollow heads are provided with crank-arms T, to which are attached arms V, which project through openings or slots in the peripheries of the heads L for the purpose of shifting the shaft, for

the purpose hereinafter explained.

The shaft is provided with curved fingers U, which may be brought against one edge of the recess in the section K to grasp the paper i at the proper time in order to carry it with the cylinder to the type-form. Through the cylinder extends longitudinally and centrally a shaft XV, which is screw-threaded at its ends i and provided with screw-threaded nuts X.

To the ends of said shaft are secured flanged wheels Y, which are separated from the ends Q of the cylinder by means of the collars Z of the side pieces A of a carriage, in which the E inkingrollers C are supported. The carriage l is provided with wheels D at the sides, which travel upon ways E at the inner sides of the press-bed. The side bars A of the carriage are connected and braced by transverse bars A. The guide-rails l', before mentioned, set up in the spaces between the wheels and the ends of the cylinder and guide the cylinder over the bed as it is passed back and forth and prevent it from leaving thc bed.

At each side of the bed of the press, near the upper edge thereof, is pivoted at one end a rail F by means of a pivot-pin G', each rail resting in a movable guide-bracket H, secured to the side of the press-bed. Below the free ends of the said pivoted rails set the short arms of two angle-levers l', which are fulcrumed to a shaft K and have their long arms working in guide-brackets L and extending upward, so as to be in the path of the cylinder when elevated. The said levers are connected with two straight levers M', fulcrumcd to the press-bed at l\", the connection being effected by means of connecting-rods P. The said levers also extend upward into the pathway of the cylinder I for the purpose hereinafter explained.

Theletter R indicates an inl; receptacle, which is located in the frame of the press-bed at the end below the inclined feed-table, and in the upper part of said receptacle sets a fountainroller S, the shaft -journals of which have their bearings in movable blocks U, which are adj ustably set in seats Y for the purpose, and confined therein by means of bindingscrews ll.

The letter X indicates a rotating ink-distributing disk, which is located in a horizontal position just in front of the ink-receptacle. The said disk is mounted upon the upper end of a vertical shaft Z,which is stepped in a bearing in a cross-beam A2, secured to ated or weighted pawl C2, pivoted to an arm D2,which is swiveled to the shaft l. To the l outer end of said arm D2 is secured one end L of a connecting-rod E2, the otherend of which i is connected with the end of an arm F2, set cured to the fulcrum-shaft li of the angle 5 levers I, before mentioned, the connectingrod E2 passing through suitable passages in 5 the beams G2, which support the form-bed H2 of the press. The said form-bed is provided l with cross-beams l2 at the bottom,which rest it upon the upper ends of the vertical adj ustj ing-screws H2, passing up through the beams G2, by means of which the type-form may be l leveled and adj Listed. The section K between l, the heads has a surfacing composed of longit tudinal staves of wood lli", to which is attached a web or blanket L2, which gives an elastic bearing to the sheet during the impression. The wheels Y at each-end of the impress-cylinder I are provided with crankpins ll 2, having loosely-fitted sleeves N2, by means of which the cylinder may be rolled i and caused to traverse the bed of the press.

At suitable points in the ways M of the press-bed are formed depressions N2, P2, and R2, into which the arms V project during the movement of the cylinder for the purpose hereinafter explained.

To one of the vertical standards B is secured a curved arm S2, which serves to actuate one of the arms V to cause the shaftP to move and the ngers lf to seize the paper to carry it forward. j

The letter T2 indicates a pawl-lever, which is loosely attached to one of journals T of the ink-fountain roller S. To the said jour nal is fastened a ratchet-wheel U2,with which engages a pawl V2, pivoted to the lever T2. The said lever T2 is connected by means of a conncctingrod W2 with one of the rods P2, so as to give the fountain-roller S a step-bystep motion to convey the ink, as more fully hereinafter explained.

The operation of my invention is as follows: The impress-roller l being in the position shown in Fig. 3 of the drawings and the paper properly placed upon the feed-table, the press is ready for use. The cylinderis then rotated by means of crank-handles, so as to traverse the pressbed in the direction of the feedtable. Just before reaching the feed-table the periphery of one of the fianged wheels Y comes in contact with the cam-arm H, operating the same, so as to elevate the rail Fand fingers E, so as to release the edge of the paper to be fed and held to the impress-cylinder. The arm V to the left, as shown in the respective figures, then comes in contact with the camarm S2, secured to one of the standards B, depressing said arm and bringing the fingers L" down upon the edge of the paper r to be seized and gripping it against the edge of the longitudinal recess in the section R of the roller l, the opposite arm Y on the right IOO IIO

entering the recess N2 and permitting the shaft P to turn sufficiently for the purpose. The inking-roller carriage in the meantime has been carried back, so as to pass the smaller inking-roller thereof over the ink-fountain roller S', taking a quantity of ink therefrom. The movement of the cylinder I is now reversed and the cylinder moved toward the right of the press, carrying the paper with it and inking the rotating type-disk, in order to uniformly diffuse the ink upon the inkingrollers forthe next operation of the press. The impress-cylinder passes over the surface of the type-form, carrying the sheet with it, until the arm V at the left drops into the recess R2 at the right of the press-bed, permit` ting the arm V at the right to be forced inward by contact With the Way over Which the cylinder travels, moving the shaft P so as to throw the fingers into the position shown in Fig. G, so as to release the sheet and drop it into the receptacle at the end of the machine. The inking-rollers on the forward movement as Well as the backward movement of the cylinder inks the face of the type ready for the next subsequent impression. In its movement toward the right the flan ged Wheels Y come in contact with the long arms of the angle-levers I turning them down and elevating the short arms, so as to elevate the rails F. The treads of the Wheels Y then ride upon the elevated rails F, so as to carry the impress-cylinder I over the surface of the type-form and clear thereof, in order not to be soiled by contact therewith, which Would result in soiling the next sheet carried vby the said impresscylinder. lVhen the impress-cylinder arrives at the position shown in Fig. 2 of the drawings, the levers M will be forced backward, dropping the short arms of the angle-levers I and permitting the rails I to fall,` so that the impresscylinder on its return movement Will ride on the Ways M and closely over the surface of the type-form, so as to take the impression upon the sheet of paper from the inked sur* face thereof. At each movement of the levers I and M the ink-fountain roller S will be moved slightly by the pavvls and ratchet T',

T2, and V2 and the connecting-rod W2, so as to take up the ink from the ink-receptacle. By the same movement through the medium of crown-ratchet B2, paWl C2, arm D2, connecting-rod E2, and arm K the inkdistributing disk will be slightly rotated, so as to present fresh surfaces to the inking-rollers at each successive movement of the impress-cylinder, and thus secure the effective. inking of the type.

It will be perceived that as constructed a press may be'furnished which will be simple and inexpensive, and which will uniformly supply the ink to the inking-rollers, distrib ute it from the same uniformly upon the face of' the type-form, and automaticallyseize the paper, impress the same upon the face of the type, and release and deliver the sheet after the impression has beenl made With the same accuracy and facility of the more expensive presses.

In some instances the Wheels D may be flanged, as shown in dotted lines in Fig. l of the drawings, enabling the tread of the Wheels to be made broader, the fianges guiding the Wheels between the top rails of the press, permitting the Ways E to be dispensed With. This construction is especially applicable to large presses where a heavy impress-cylinder is used.
